Gram-Force Millimeter [gf·mm]

Gram-force millimeter (gf·mm) is a unit of torque or moment of force used to measure very small rotational forces, typically in delicate mechanical systems or precision instruments. It represents the torque produced when a force of one gram-force (gf) is applied at a distance of one millimeter (mm) from a pivot point.

This unit is particularly useful in fields such as microengineering, watchmaking, electronics, and small-scale mechanical testing, where tiny torques need to be accurately measured and controlled. For example, gf·mm is often used to specify the torque for miniature screws or the resistance of small mechanical components.

Although the newton-meter (N·m) is the standard SI unit for torque, gf·mm offers a practical scale for extremely low torque measurements, providing precision that is more intuitive when dealing with tiny forces and distances. To convert, 1 gf·mm is approximately 9.80665 × 10⁻⁶ N·m.

Using gram-force millimeters allows engineers and technicians to ensure proper functioning of small devices by preventing over-tightening or insufficient torque application.

Newton Meter [N·m]

Newton meter (N·m) is the standard SI unit of torque, measuring the rotational force applied to an object around an axis. It combines force in newtons (N) with distance in meters (m) from the axis of rotation. One newton meter represents the torque generated when a force of one newton is applied perpendicularly at a distance of one meter from the rotation axis. This unit is widely used in physics, mechanical engineering, automotive design, robotics, and industrial applications to quantify torque, rotational performance, and mechanical efficiency. A higher N·m value indicates stronger torque and greater ability to cause angular acceleration, while a lower value signifies less rotational force. Engineers and designers use this measure to calculate torque requirements, optimize machinery, ensure component stability, and prevent mechanical failure. By linking force and rotational distance, newton meter provides a practical, precise, and universally recognized standard for analyzing and managing torque in a variety of mechanical, industrial, and scientific applications.
